分布特征我国水能资源虽然丰富 ,但时空分布不均 ,质量不高 ,主要反映在以下两个方面 :一是空间上分布不均衡 ,主要集中在经济落后、交通不便的西南地区 ,约占全国总量的 67 8% ,其次是中南和西北地区 ,分别占 1 5 5%和 9 9% ,而经济发达、用电负荷集中的我国东部的华东、东北 Distribution Characteristics Although rich in hydropower resources, China’s hydropower resources are unevenly distributed, with low quality, which is mainly reflected in the following two aspects: First, the spatial distribution is uneven, mainly concentrated in the southwest region with backward economy and inconvenient transportation, accounting for approximately 67.8% of the total, followed by Central and South China and the Northwest, which accounted for 155% and 99%, respectively, and the eastern and eastern parts of eastern China where the economy is developed and the electricity load is concentrated.
